This only affects root. For security reasons, by default, root is not
allowed to map to root across NFS. Only allow it when you know your LAN
is well secured.

Yes, that is the problem. On my three box network I solve it by creating
all accounts on a single box, then using rsync to distribute. There are
three password files and the /etc/group file to keep in sync. I can't
recall the names of all three password files, I think it's /etc/passwd,
/etc/passwd.master, and /etc/passwd.db. You'll find them.
